Definitions

  • a self-releasing ski binding for securing a shoe to a ski, comprises first and second coupling means, said first coupling means being provided centrally along the shoe and said second coupling means being disv posed at an opposed position on the ski, said first coupling means being resiliently latched to said second coupling means, said second coupling means including means for manual disengagement from said first coupling means.
  • the present invention relates to a self-releasing ski binding which differs from the known bindings of that kind in that coupling means, which are connected to each other elastically and powerfully, are arranged in the centre part of the ski shoe, one portion being fixed to a sole part of the ski shoe and the other oppositely to the ski, whereby for release the coupling means react to certain turning momenta caused by falls during skiing, and furthermore that there is provided an operating member which stands in an operating connection to one of the coupling means and by means of which the coupling can be released at will by hand.
  • FIG. 1 is a side view of the self-releasing ski binding, seen from the outer face of the shoe, in a first example of construction
  • FIG. 2 is a plan view corresponding to FIG. 1;
  • FIG. 3 is a view of the self-releasing ski binding from the back
  • FIG. 4 is a view from below of the ski binding, with part shown in section along the line IVIV in FIG. 3;
  • FIG. 5 shows single discs of the springs put together pair-wise, and seen in axial section and on a larger scale
  • FIG. 6 is a view of the ski binding from the back in a second example of construction.
  • FIG. 7 is a side view thereof with part in section.
  • the latching member 3 has a hollow cylinder 4 which passes through the sole of the shoe 2 in a transverse throughhole 5.
  • a conical pin 6 which is provided with a slightly rounded frustum of a cone 6 which protrudes at one end of the hollow cylinder.
  • the hollow cylinder 4 is tightly connected to the main steel plate 22 of the sole of the sole part 2 by welding or screwing on. 7 is a locking screw, accessible from below, which connects the hollow cylinder with the conical pin 6.
  • the other end of the hollow cylinder 4 has a longitudinally movable conical pin 8 which has on its outer part a slightly rounded frustum of a cone 8' and which, by its inner end and by an axially threaded bolt 23, is connected in a screw-adjustable manner with a piston 8" which can move in the hollow cylinder 4 and has an axial threaded hole 24.
  • the piston 8" is secured against coming out of the hollow cylinder 4 by a flange 9 which narrows the opening of the hollow cylinder, and it also bears against a pressure spring, 10.
  • the pressure spring 10 is assembled from the conical ring discs or conical spring washers made of spring steel sheet metal (FIG. 5).
  • the ring discs 10 are joined together in pairs or in bundles l0 i.e. matched according to shape.
  • a comparatively soft springing can be achieved by the ring discs 10' which support themselves in pairs with their concave sides against each other.
  • some ring discs can be assembled in bundles as at the left part at 10" in FIG. 5, whereby a more exact fit of the spring length to the length of the hollow cylinder is possible and simultaneously a harder springing can be achieved.
  • By the partly pair-wise and partly bundled joining of the ring discs 10 a coarse adjustment of the springing to a softer or harder release of the ski binding is possible.
  • a fitting 11 in the form of a U-bow which is fixed on the upper part of the ski 13 by means of two screws 12, as shown by FIG. 3.
  • a latch jaw 14 With a hollow conical holding seat 14 in which the rounded frustum of a cone 8' of the latching member seats.
  • the other side piece 15 of the fitting 11 forms a bearing fork in which a latch jaw 16 is journalled to pivot about an axle pin 17.
  • the latch jaw 16 has a hollow conical holding seat 16 in which the rounded frustum of a cone 6' of the latching member 3 engages.
  • the pivotable latch jaw 16 is adjacent to an eccentric 18 of a tension lever 20 which is pivotable in the bearing fork 15 around a pivot pin 19. In the swung-in position of the tension lever 20 the latch jaw 16 is in a locking position. After the tension lever 20 is swung out, the latch jaw 16 is pivotable into its release position whereby the binding can be opened at will and rapidly.
  • the sole 2 of the shoe lying against the fitting 11 by its articulation part allows also a securing of the ski shoe position by inserting two spacers 21 and gives it a forward tilted position.
  • the tilting of the release can be adjusted to the front or to the back.
  • the manufacturing costs of the above described ski binding are low and mounting on to new or old skis can be carried out quickly.
  • the-skis are not weakened by a number of holes for receiving fixing screws in the region of the ski binding.
  • the tension lever is, as a rule, always reachable by the hand in order to effect uncoupling or release at will.
  • the above described self-releasing ski binding can also be provided with an auxiliary base plate 25 which serves as a carrier of a conventional non-self-releasing ski binding as well as accepting the latching member 3 of the self-releasing ski binding.
  • a base plate 25 is provided with a known holding member 26 at the back and with a similarly operable holding member 27 at the front.
  • the base plate 25 has a U-shaped cross section whereby the profiled flanges 25' which point downwards are connected to each other by a crosspiece 28 at the back, and by a crosspiece 29 at the front. These crosspieces 28, 29 serve to seat plate 25 onto two spacing pieces 30, 31 arranged on the ski.
  • the fitting 11 with the integral latch jaw 14 and the bearing fork 15 with the usual latch jaw 16 and the eccentric tension lever 20 is also in this construction fixed on the ski 13, while the latching member 3 engages through the profile flanges 25 of the fitting 11 in corresponding holes and is connected firmly by welding, hard soldering or screwing onto the fitting 11.
  • the combination comprising a ski, a ski boot, and a binding for connecting said boot to said ski, said binding comprising a. a hollow cylindrical member in the sole of said boot, the opposite ends thereof being substantially coterminous with opposite edges of the sole,
  • stop means preventing said piston from sliding out one end of said cylindrical member
  • a plug removably secured in the end of said cylinder member opposite said one end, said plug having a frusto-conical surface extending radially from said opposite end of said cylindrical member,
  • fitting means arranged on said ski including a pair of spaced conical recesses therein for receiving said conical surfaces of said pin and plug,
  • said fitting means comprises a pair of latching jaws, one of said latching jaws being pivotally mounted, one of said spaced conical recesses being located in each of said latching jaws, and cam means including a lever arranged to abut against said pivoted jaw for selectively retaining said jaw in engaging position.
  • said fitting means comprises a U-shaped member secured to the upper part of said ski, said U-shaped member including said latching jaws.
